2026 F1 powertrain regulations approved by FIA World Motor Sport Council RaceFans

The FIA ​​World Motor Sport Council today approved the first version of new Formula 1 powertrain regulations due to come into force in 2026.

The 2026 F1 season will see the introduction of a new power unit formula – the first since the FIA ​​introduced the current V6 turbo hybrid engines which are still in place today in 2014.

The revised power units will increase electrical power generated by up to 50% over current levels, with the FIA ​​saying the power units will maintain “similar performance” to existing engines.

The powertrain introduced for the 2026 season will continue to use the current 1.6-litre V6 internal combustion engine, but with a reduced fuel flow limit that will produce around 400kW of power. The current MGU-H component of the hybrid system will be removed entirely, as planned, while the total power generated by the power unit’s Energy Recovery System (ERS) will increase to around 350 kW.

The FIA ​​says all racing fuels used for the new 2026 power units will be “100% sustainable fuels”, while fuel flow rates will now be measured and limited based on energy, rather than mass or weight. volume of the fuel itself.

The introduction of new engines will also be accompanied by a change in sporting regulations. From 2027, all drivers will continue to be limited to just three internal combustion engines for a season, along with three turbochargers and two control electronics units and energy reservoirs. However, drivers will be limited to three “exhaust assemblies” – down from the eight exhaust systems currently allowed – while they will also be limited to just two MGU-Ks, one less than currently. For the 2026 season alone, all drivers will be awarded an additional item of each component.

Additionally, new powertrain financial restrictions will come into effect at the start of 2023, limiting all powertrain suppliers for the 2026 season to a total annual spend of $95m (£78.6m) for 2023, 2024 and 2025, the ceiling increasing. at $130m (£107.6m) from the 2026 season.

FIA President Mohammed Ben Sulayem said the new powertrain regulations were designed with durability and roadworthiness in mind.

“The FIA ​​continues to drive innovation and sustainability forward – across our motorsports portfolio – the 2026 Formula 1 Powertrain Regulations are the most high-profile example of this mission,” said Ben. Sulayem.

“The introduction of advanced powertrain technology along with sustainable synthetic fuels aligns with our goal of delivering benefits to road car users and achieving our goal of net zero carbon by 2030. Formula 1 is currently experiencing immense growth and we are confident that this regulation will build on the excitement that our 2022 changes have generated.

The first draft of 2026 powertrain regulations will likely pave the way for Audi and Porsche to move forward with widely anticipated plans to join Formula 1 as powertrain manufacturers as soon as the new formula is introduced.
